Bug 140723 – SVG overflow:visible mouse events broken

• Status: RESOLVED
• Resolution: CONFIGURATION CHANGED
• Component: SVG

This is related to #96163 (https://bugs.webkit.org/show_bug.cgi?id=96163)

When `overflow: visible` is set on an SVG element, it now renders the overflowing content, 
however mouse events do not work.

In the linked example, hovering over the overflowed part of a `rect` node does not cause 
the `:hover` pseudo class to apply, and clicking in the overflowed part of a `rect` node
does not supply the correct event target for the event handler in the JS. Clicking on
parts of the `rect` within the SVG node does work as expected.

Blink fix https://code.google.com/p/chromium/issues/detail?id=231577

Dirk, unsure what you mean. Are you just referencing the blink fix to facilitate fixing  webkit or are you suggesting that this issue has already been fixed?

This is meant for the developer fixing this bug.

Cool, thanks for clarifying.

I'm wondering if there's any movement on this bug at all? Anything roadmapped? I'd love to see a fix for this.

I am able to reproduce this bug in Safari 15.5 on macOS 12.4 by performing following steps:

1) Load Codepen from the Description or URL
2) Hover the mouse on "BLACK" square on the outer edge (outside of red square - which is overlapped by black square)
3) Hover will not be activated (except for first - top left) and clicking with give "BODY" as result

--> Expected Result (Which is consistent across all other browsers - Chrome Canary 105 and Firefox Nightly 104):

hover to be activated even if the mouse cursor is outside on the black square portion

--> Actual Result:

Hover only activate for nodes when mouse is on red square or inner part of black box covering red square

If I am testing incorrectly, please retest accordingly. Thanks!

This actually seems to work properly, at least in Safari 16 on macOS 13 Beta. I can click in areas outside of the SVG, and see things like BODY, P, LI, and so forth.

I think this behavior has progressed.
